In each of the following letter series, some of the letters are missing, which are given below it. Choose the correct alternative.
D_F_DEE_D_EF_DE_F
Explanation:
If we split the alphabets in a group of 3 we get following arrangement:
D__F | __DE | E__D | __EF | __DE | __F
Now, if we put option 3, we get:
DEF | FDE | EFD | DEF | FDE | EF
If we see the pattern it is consistent in the sense that the third alphabet in each subset is the first alphabet in the next subset and the order is cyclic. (D, E, F or F, D, E or E, F, D).
Hence, option (c).
